UPDATE: Better quality Twilight Princess.
These pdfs have all the text intact and I found a lot more of them. There aren't just WII games, there are DS and a few other consoles.
My way to find them is to put this before my search term:
I was looking around on nintendo's website on some really old stuff related to the WII version of Legend of Zelda Twilight Princess and I found a pdf of the instruction booklet.
I might index all of Nintendo's game manual pdfs for WII on a website but it would take a long time.
